At least five Japanese firms have stepped up their production to up with demand for components and chemicals for semi-conductors.
Approximately 60 percent of the materials and components are exported, primarily to Taiwan and other key manufacturing hubs, with the rest used domestically.
It follows Japanese technology companies taking control of the development and production of the advanced materials required for cutting-edge chips.
Nearly the entire global supply of specialised coating and other critical components in the most advanced chips comes from the Land of the Rising Sun.
The nation has a market share of 60 percent or more of the global market for another 70 advanced materials.
Two Japanese companies alone – Shin-Etsu Chemical and Sumco Corporation – control 60 per cent of the global market for silicon wafers.
